Description

【発明の詳細な説明】 （産業上の利用分野） 本発明は、泥漿鋳込み成形体を徐々に乾燥する徐乾室
に関する。Description: TECHNICAL FIELD The present invention relates to a slow drying chamber for gradually drying a slurry cast molded article.

（従来の技術） 衛生陶器製造工程における成形体は、型鋳込み→脱型
→乾燥→焼成の順で処理される。更に、前記乾燥は、徐
乾工程と本乾燥工程に区分される。(Prior Art) A molded article in a sanitary ware manufacturing process is processed in the order of mold casting → demolding → drying → firing. Further, the drying is divided into a slow drying step and a main drying step.

脱型後の成形体は多量の水分を保有しているので、通
常の乾燥では表面の乾燥と内部からの水分の抜けとのバ
ランスが崩れ、成形体に亀裂が入るなどの不都合があ
る。Since the molded article after releasing the mold has a large amount of water, the ordinary drying has a problem that the balance between the drying of the surface and the loss of moisture from the inside is broken, and the molded article is cracked.

よって、多湿雰囲気内で成形体を緩やかに乾燥させる
徐乾室が設備される。Therefore, a slow drying chamber for gently drying the molded body in a humid atmosphere is provided.

従来の徐乾室は、室内へコンベア若しくは台車で成形
体を搬入し、これら成形体を平面配列して、所定時間保
留するものである。In a conventional slow drying chamber, a formed body is carried into a room by a conveyor or a cart, these formed bodies are arranged in a plane, and are held for a predetermined time.

この平面配列式徐乾室は、高さ寸法が小さいので室内
の雰囲気はドラフト効果を受けにくく、雰囲気の湿度管
理が容易なので、従来は好んで設備されている。Conventionally, the flat array type drying chamber has a small height, so that the atmosphere in the room is hardly affected by the draft effect and the humidity of the atmosphere is easily controlled.

（発明が解決しようとする課題） しかし、成形体の収納時間が極めて長い為に、前記平
面配列式徐乾室は大きな設置面積を必要とし、成形体製
造工場が大型化する等の不都合がある。又、乾燥時間の
異なる成形体を同室内で乾燥する場合、所望の時期での
成形体の搬入・搬出が容易にできなかった。(Problems to be Solved by the Invention) However, since the storage time of the molded body is extremely long, the planar array type slow drying chamber requires a large installation area, and there is an inconvenience that the molded body manufacturing plant becomes large. . Also, when drying molded articles having different drying times in the same room, it is not easy to carry in / out the molded articles at a desired time.

そこで、本発明は、徐乾室のスペースが小さくかつ成
形体の搬入・搬出が容易にできる成形体用徐乾室を提供
することを目的とする。Accordingly, an object of the present invention is to provide a molded article gradual drying chamber in which the space in the gradual drying chamber is small and the loading and unloading of the molded body can be easily performed.

設した送風機とから構成する。(Means for Solving the Problems) In order to solve the above problems, the present invention provides a shelf having a space for accommodating a plurality of molded bodies, a shelf capable of running on a fixed path along the front surface of the shelf, and ascending and descending. In a molded article elevating and moving means having a receiving / delivery means capable of moving forward and backward in the direction, a humidifying means for adjusting indoor humidity, and a slow drying chamber for a slurry cast molded article having an atmosphere circulating means for circulating an indoor atmosphere, The atmosphere circulating means includes a duct for sucking the atmosphere from the upper part of the drying chamber and discharging it to the lower part of the drying chamber, and a blower interposed in the duct.

（作用） 成形体昇降手段にて複数の成形体を垂直に配列して徐
乾室に収納する。(Operation) A plurality of compacts are vertically arranged by the compact lifting means and stored in the drying chamber.

雰囲気は湿分に富み、微細霧滴が下降しようとする
が、雰囲気循環手段にて適度に循環・撹拌される。よっ
て、均質な雰囲気が高所の成形体及び低所の成形体を等
しく徐乾乾燥する。The atmosphere is rich in moisture, and fine mist droplets tend to descend, but are appropriately circulated and stirred by the atmosphere circulation means. Therefore, the homogeneous atmosphere uniformly and gradually drys the compact at a high place and the compact at a low place.

更に、上部のダクト及び送風機によって徐乾室の上部
から雰囲気を吸出し、ダクトの下部から吐出するので、
徐乾室内の湿度を均一に保つことができる。Furthermore, since the atmosphere is sucked from the upper part of the slow drying chamber by the upper duct and the blower and discharged from the lower part of the duct,
Humidity in the drying room can be kept uniform.
